One of the guy introducing "The Crew" at the E3 told one journalist : "you have an iPad? How does it feel whan you don't have WIFI or 3G for it? It feels empty and dead right? I believe consoles are becoming about online now and in a few years you'll understand what I meant here".
Because it was made to be taken anywhere you go. As I see it, Microsoft is marketing their new console for online gaming. It worked for Diablo 3 and Sim City, don't see why they wouldn't try to pull this one.
